Psi2ir: do not sort descriptors for fake override generation

Descriptors are already supposed to be sorted in scopes. The problem is
that rendering descriptors for sorting takes a lot of time (~1.5% of
total compilation time of intellij with JVM IR), and simple heuristics,
like comparing by names first, don't fully help with it.
